Hey Metricton, I wish I saw your post before last week as I painstakingly went through the same process to get it functional the last few days.
I have got it to work when the Host and Client Beacons are created on two game instances without any map options.
However, when the Host is made a listen server and the beacons are then created, client shows a connection failure message when trying to connect to a Host Beacon.
Is this an issue with the FURL being incorrect on the Client beacon due to additional options added to the server URL i.e. listen? Any suggestions as to how to actually set the client URL correctly as right now mine is just set to blank?
